Interesting idea. The approach assumes that the only way governments censor is by inspecting destination IP addresses (or DNS, etc.), which may be true for some countries, but not others. If the censoring government were to operate a huge TLS proxy, then I can imagine an ISP doing a Telex-stripping attack that downgrades the tagged-TLS connection to a normal one. I think this can be detected...
